HAT-PIN PROTECTOR.

To all whom it m ay concern: 7 p Be it known that I, Knzo YOSHINAGA,

, asubject of the Emperor of Japan, residing l at San Francisco, in thecounty of San Fran cisco and State of California, have invented new anduseful Improvements in Hat-Pin Protectors, of which the following is aspecification.

The present invention'relates to improvements in hat pin protectors, theobject of this characterwhich will besimple in 0on l struction,efiective and convenient in operation, and ornamental-- in appearance.

In the accompanying drawing, Figure 1 is a side view of the protectorappliedto a hat pin; Fig. 2 is a longitudinal sectional view thereof;Fig. 3 isa cross-sectional view on the line 33 of Fig.2.:

hat pin of ordinary construction.

Myimprovedprotector comprises a tubu-. lar body 2, the bore 3 of whichreceives the a pointed endofthe pin, andwhich is contracted at the outerend,as shownat 4, to engage the extreme end of said pin and arrest themovement of the protector upon the pin. To facilitate the passing, oftheprotec-- tor upon the pin, its outer end is threaded and screwed intoa threaded central boss 6 of a concavo-convex head.

The inner end of the body of the protector is enlarged transversely asshown at 8, and" formed with three radially extending guide ways 9, inwhich are received balls 11. The

outer side of said enlarged portion isconical and tapers toward the headof the pin, said guideways opening into said outer tapering surface ofsaid enlarged portion. Surrounding said conical enlarged portion is avconical closure 12 having a neck 13. 1 1 indicates a spring formed atthe center with a hole 15 surrounding said neck 13, and at the. endswith holes 17 surrounding the reduced portion 4 of the end of the bodyof the protector, and pressed between the boss 6 and the shoulder 18formed by said reduced portion 4:, the tension of this spring acting todraw a the closuretoward the head of the protector.

Specification 0': Letters Patent. AppIication filed February 3, 1913.Serial No. 745,876.

Referring to the drawingfl indicates a Patented Dec. 1, 1914.

i The mode of use of the protector can be readily understood from theforegoing description. Whenthe pointed end of the pin is inserted in thebore of the protector, the

the direction of the protector head, beingretained in that said positionby the conical wall ofthe closure, which in turn is pressed toward saidhead by said spring. The ten-- sion of said spring, through'the mediumof the closure, causes said balls to press against the pin withsufficientforce to prevent acci- The pin can be removed,

"balls engage the surface of-the pin, and are, i by frictional contacttherewith pressed in form a stop for the pointed end of'the pin, i

a cap screwed to said end of the tube, the other end of the tube beingenlarged and formed entirely therethrough with radially extendingopen-ended guideways, balls in said guideways, a longitudinally movablemember surrounding said tube and formed with a neck, theinner surface ofsaid member being conical, a curved spring one end of which engages saidneck and the other is fixed, and said spring extendingconvexly outwardbetween its ends in a position to be manually flattened to move saidmember longitudinally, said member being so arranged that by saidlongitudinal movement its inner surface is withdrawn from said balls. 1r
